title: Association of rs2200733 at 4q25 with atrial flutter/fibrillation diseases in an Italian population.
abstract: BACKGROUND
  Atrial fibrillation (AF) and atrial flutter (AFL) are common cardiac conduction disorders affecting many people. Recent studies on sporadic cases of AF/AFL showed a significant association of the single nucleotide polymorphism rs2200733T with the disease, suggesting a genetic factor in the development of the disease.
  
  
  OBJECTIVE
  To determine the association of rs2200733 with AF/AFL derived from an Italian population sample.
  
  
  METHODS
  78 patients with AF/AFL and 348 controls took part in the study.
  
  
  METHODS
  Genetic case-control study.
  
  
  RESULTS
  The results indicate that there is a positive, significant association between the rs2200733 T allele and patients with AF/AFL of Italian origin (allelic p<0.001 with OR = 2.17).
  
  
  CONCLUSIONS
  These results derived from a sample of the Italian population agree with previously reported findings from an Icelandic study, which also found that the minor allele rs2200733 was associated with AF/AFL disease.
